Well if you want Real things then yes. You can however go to your personal paradise at any time and just conjure whatever you desire at will. It just can’t leave your paradise.
Also, as said on one of the first pages in this scene; angels don’t need food (or water or anything else for that matter.) So it’s not like you’ll ever be missing anything material. Some people just really desire/Prefer things that are real, and doesn’t simply feel and look the act. Real products however will cost someone else’s time and effort to produce, and they’d like to be repaid for that, so yeah money.
